title: 14-Meth-oxy-4,6-dimethyl-9-phenyl-8,12-dioxa-4,6-di-aza-tetra-cyclo-[8.8.0.0(2,7).0(13,18)]octa-deca-2(7),13,15,17-tetra-ene-3,5,11-trione.
abstract: The title compound, C23H20N2O6, crystallizes with two mol-ecules in the asymmetric unit in which the dihedral angles between the mean planes of the pyran and phenyl rings are 66.6 (1) and 61.9 (1) °. The fused pyrone and pyran rings each adopts a sofa conformation. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules, forming a two-dimensional network parallel to [001].
